Description

[Detailed description of the invention] In this invention, the press-formed tile base is suctioned by a suction cup device whose inside is tilted to negative pressure, conveyed from a conveyor, and then packed into a sagger when the negative pressure is released. This invention relates to a negative pressure suction device in an automatic sagger filling device for tile substrates.

As illustrated in Fig. 1, a conventional negative pressure suction device for an automatic sagger filling machine for tile substrates has a large number of suction cups 2 attached to the bottom surface, and suction holes 3 provided through the top surface are connected to a flexible hose. Several suspension rods 5 are installed on the top surface of the box-shaped suction cup device 1 connected to a negative pressure source such as a vacuum pump (not shown) by 4, and each suspension rod 5 is inserted into a hole 7 made transparently in the support plate 6. A nut 8 screwed onto the protrusion through the suction cup is brought into contact with the upper surface of the support plate 6 to allow it to freely float up and down.Brackets 9 are fixed to both sides of the suction cup device 1, and a nut 10 is attached to each bracket 9. Two vertical rods 11, front and rear, tightened by
It has a structure in which a rod-shaped stopper 12 is horizontally spanned and welded to the lower end, and the support plate 6 is driven by vertical and horizontal air cylinders (not shown) to move the suction position on the conveyor and the sagger in an inverted U-shaped path. The suction cup device 1 moves back and forth between the two positions of packing position B.
By tilting the inside to negative pressure, the suction cup 2 sucks the tile base material a on the conveyor, and then transports it to the sagger filling position B, and as shown in the figure, the tile base material a is placed in the sagger b.
By repeating the operation of holding the tile material and releasing the negative pressure, filling the sagger is automatically carried out. By contacting the edge and regulating the height relative to the sagger b, it is possible to prevent the tile base a from being damaged due to the weight of the suction cup device 1 acting on it. In this way, the stoppers 12 on both sides of the suction cup device 1 are essential for safely storing the easily damaged tile base a into the sagger b, but when suctioning the tile base a on the conveyor, If the spacing between the sent tile substrates a is narrow, the tile substrates a to be adsorbed
There is a risk that the tile base a following the tile base a may be pressed by the stopper 12 and damaged, and in order to prevent this, the interval between the tile bases a on the conveyor must be increased. This had the disadvantage of reducing work efficiency.

The object of the present invention is to provide a negative pressure adsorption device with a novel structure that eliminates such drawbacks.

Below, Figures 2 to 4 show an embodiment of the present invention.
This will be explained in detail based on the figures.

The suction cup device 1 of this embodiment has the same structure as the conventional example shown in FIG.
0, the vertical rod 11 and the stopper 12 are omitted, and a small air cylinder 20 is attached downward in their place. This air cylinder 20 is the fourth
As shown in detail in the figure, a piston 26 is fitted into a cylindrical cylinder body 21 with an open bottom surface and a mounting bracket 22 protruding from both sides, and a piston rod with a hexagonal cross section is fixed to the center of the bottom surface. A rod-shaped stopper 30 is screwed to the lower end of the piston rod 27 so that its length can be adjusted. A compression spring 32 fitted into a groove 28a formed on the upper surface of the cover plate 28 contacts the lower surface of the piston 26, and its elastic expansion force causes the piston 26 to move into the cylinder. It is pressed against a boss 23 formed in the center of the top surface of the cylinder body 21, and has a structure in which a nipple 25 is screwed into a vent hole 24 provided through the outer periphery of the upper end of the cylinder body 21. The nipple 25 is connected to a pressurized air supply source through a hose (not shown) fitted to the nipple 25.

This air cylinder 20 always has a compression spring 3
The piston rod 27 is contracted upward by the elastic expanding force of 2, and as shown in FIG.
When picking up the tile base material a at the suction position A on the conveyor c, the stopper 30 is spaced upward from the conveyance surface of the conveyor c, so that the tile base material a is sent following the tile base material a to be picked up. Even if the tile base material a' approaches, the stopper 30 will not press against it and damage it. As shown in FIG. 3, at the sagger filling position B, when the conveyed tile material a is placed in the sagger b by releasing the negative pressure, the pressurized air is A switching valve (not shown) installed in a hose between the supply source and the supply source is operated to supply pressurized air to the upper surface of the piston 26, and the pressure causes the piston 26 and piston rod 27 to move against the elasticity of the compression spring 32. As the piston 26 moves downward, the lower surface of the piston 26 comes into contact with the cover plate 28 and the stopper 30 comes into contact with the edge of the sagger pot b, as shown by the chain line in FIG. This prevents the tile substrate a from being pushed too hard and damaged.

In the above, instead of the air cylinder 20,
Other actuators such as hydraulic cylinders or solenoids may be used, and the stopper may not be fixed to the actuator but may be moved up and down via a link mechanism.

Further, the stopper 30 of the present invention may be installed only on the carry-in side of the conveyor c, and a conventional fixed stopper may be provided on the other side.

As explained above, in the negative pressure suction device for an automatic sagger filling machine for tile substrates of the present invention, at least one of the stoppers provided on both sides of the suction cup device is driven by an actuator such as an air cylinder. Since the structure allows the stopper to move up and down, it is possible to prevent the tile base from being damaged due to a large load when filling the sagger. Interference with the tile base can be reliably prevented, and the tile base can therefore be conveyed continuously on the conveyor, resulting in the effect of improving work efficiency.
